IMPROVEMENT IN MEAT-SHOPPERS.

Specification forming part of Letters Patent No. 185,104, dated December 5, 1876; application filed April 1, 1876. l

To all whom it 'may concern:

Be it ,known that I, SHUBAEL E. HEWEs, of Hoopeston, in the county of Vermillion and State of Illinois, have invented a Combined Ghopping-Bowl and Butter-Worker, of which the vfollowing is a specification:

This invention relates to a combined chopping-bowl and butter-worker for household use, in which the frame for the operating mechanism and the bowl or tray are secured to Vbed-plate, which may be clamped to a table or bench; and it consists, first, in a meat-chopper adapted to receive a muller, to convert it into a butter-worker; second, in the combination of the bowl, bowl-seat, having arms and legs, and hooked fastenings, for securing the bowl to its seat; third, in the combination, with the crank-rod, of a screw-threaded socket, which firmly clamps the knife in a slot in said crank-shaft, so that it is easily removable for sharpening or cleansing, or adjusting to the bottom of the bowl; fourth, in a muller, for working the milk out of' the butter, constructed in two parts, of peculiar shape, and secured to the knife, one on each side, by screws, as hereinafter set forth; fifth, in the combination, with the operating` mechanism, ofa vertically-moving crank-rod, to which the knife and muller are secured, and a hinged lever-arm, whose end is pivoted in a slot in 4 the crank-rod, to give a drawing stroke to the rod when down and just before it rises; sixth, in the combination, with the operating mechanism and crank-rod, of a jointed lever, for operating a shaft to which is secured a motory lever for revolving the caster, the jointed end ofthe lever being pivoted in a slot in the crank-shaft, the length of which is adjustable, to regulate the distance the motory end of lever will move, and thus cause the rotary movement of the bowl to go fast or slow, as required, seventh, in the use of a spiral or rubber spring, applied to connect the pawl and motory lever to hold them to their work.

Figure 1 is a transverse section of the machine on the line 1 l, Fig. 2, the full and dotted lines, respectively, showing the parts in their lower and upper limit of motion. Fig.

2 is a vertical section on the line 2 2, Fig. l.

Fig. 3 is a plan View of the combined machine. Fig. 4 is a longitudinal section on the line 4 4,

Figs. 1 and 2. Fig. 5 shows a modified formA of spring-holders, for securing the bowl in its seat. v

A may represent the bed-plate, to which is secured the frame B for supporting the operating mechanism, and the pivot-block C, on which the caster turns. The block may be made in one piece with the bed-plate. D is the caster, turning on the pivot E, and having arms F, to form the seat for the bowl or tray G. The caster is supported at the edge by legs H, which form bearings for friction-wheels I, running on the bed-plate. J are elastic bands, removably fastened to the arms F by hooks, and having hooks J which fasten over the edge of the bowl or tray, to hold it in place when in use, and render it easily removable when desired.

A modification of the mode of securing th bowl is shown in Fig. 5, in which springhooks K are attached to the arms of the caster, and pass through sockets L on the bowl. M may represent a cog-wheel, supported in the frame B and turned by a crank. This wheel gears with a wheel, N, on a crank-shaft, O. P is a crank-rod, attached to the crank-shaft by a strap, and tapering at its lower end to receive a screw-threaded socket, Q, of corresponding taper, to clamp the knife lc in a slot in said rod, so that it can be removed and adjusted at pleasure.

R It may represent the two parts of the muller, for working the milk out of the butter, which are clamped together on each side of the knife when the machine is used as a butter-Worker by screws S passing through holes in the knife. T represents a slotted lever-arm hinged to a cross-piece, B', in the frame B at one end, and pivoted at the other in a slot, U, in the crank-rod P to form a center or pivot for it, and give a drawing stroke to the knife ,ing cut tothe knife.

imparts'a rotary motion to the boxvl G. It receives a reciprocating motion from the crossshaft W through a depending lever, y', and

acts on the ratchet-wheel teeth Z on thec'aster D, its outer end being supported by a. rim, Z'.

a represents a pawl for pmwenti'ng;n backward motory-lever end are held to theratchct-wheel` by a connecting-spring, c, of rubber or' any other suitable material applied between or around the paw] andA motorylever extension a of said lever end, as shown in Fig. 4.

The extent of movement of the lever end Y is adjusted by the length of the slot X, which isregu-lated by means of a pinvX, entering aseriesrof holes,l e, in` Vthe crank-rod P.` gis a curved scraper attached to the cross-piece B for scraping thesides of the bowl as it revolves, andrturningthe contents; towardnthe center.

Operation: When thermachine is to be used itis clamped to a table or bench, and, if for choppingthe muller is removedandV the bowl lled` withV the material` to,` beV chopped, the crank turned, and: the crank-shaft caused, through intermediate gearing, to revolvey to impart a reciprocating motion to the crankv rod to which the knife is attached. When the knife is near the end of its downward stroke, and at the beginning ot' the upward stroke, the pivotofthe hinged lever-arm- T, said lever-arm being at rest, comes in! contact with the top ot the ,slot in the lower end of therod P, and acts as a. center to give a draw'- As the4 crank-rod is reciproca-ted the jointedA lever is movedl up.` and down, and imparts` motion to the horizontal motory end of the lever, which, acting outhe ratchet-wheel teethon the caster, revolves it.

The distance the motory end of the lever moves, and the movement of the bowl, are regulated by the length of the slot X, which is adjusted. according as it is `desired for the bowlA to revolve with greater orW less speed. As the bowl revolves the contents are turned back-from the sides and under the knife by the curved scraper.

When the machine is used as a butterworker the muller is attached to the knife, the butter to be worked is placed in the bowl, andthe machine operated as before. l

What I claim as new, and desire to secure by Letters Patent, is-

1'. Thewmeatchopper adapted for conversion.` into a butter-worker by the addition of a muller, as herein set forth.

2. The combination of the bowlseat D, arms F, legs H, bowl G, and hooked fasteningsfor securing the` bowl tot its seat, substantially in the manner described.

3;.The combination witlr the crank-rod P, having a tapering end screw-threaded, andthe screwthreaded socket (2,., to firmly; clamp the knife in place,k as set forth.`

4. The muller RB! constructed in two parts, and adapted tobe removably secured to a chopping-knife,l for` they purpose` specified.`

5. The combinationof the operating mech anism M N 0, the crank-rod P, having slot U, and the lever T hinged` at one end to the frame, and pivoted at the other i-n said slot, for the purpose sety forth. f

6. rEhe combinationF of the operating mechanisinM N,(),.the-crankrodhaving adjustable slot X the jointed lever V W, crossi shaft W', depending arm 1 l, and pawl y, for imparting a rotary movement to. the bowl, as set forth.

7. The spring @applied around the pawl, and an extension, a', of tele ratchet,tohold them4 both to their Work, s set forth.
